Interesting question and observation from a friend:
Have you, or other folks in the field, looked at homeland security as a function rather than a substantive “new” field?
In other words, maybe homeland security should stop trying to carve out substantive turf and look at itself as the great coordinator. Intelligence, military, borders, state law enforcement, local law enforcement, coast guard, TSA, emergency preparedness, etc. do not really have a good way to communicate, share information, see all the dots – let alone connect them.
Perhaps that is the purpose of the “homeland security,” to have enough visibility and interaction with all those players so sharing is happening when it is useful, but not just as a meaningless unfiltered information dump. That would actually be a very difficult job, and in many ways, precisely the intent of the fusion centers.
One thing is certain though, if that were expressly DHS’s mission and it was roughly limited to that mission, they would have a much better opportunity for success.
